I guess sacking Ten Hag had an instant positive effect on the team, as Manchester United is currently leading against Leicester 5-2 in the EFL Cup game. Leicester is one place below Man United in the league table.
Poor attacking power was United's main problem last season and continued into this season, so it's strange to see them scoring 5 games (possibly more as there's still 10 mins left to the final whistle). Perhaps players try to impress the new manager - Ruben Amorim.
Currently the team is led by an interim manager, Ruud Van Nistelroy.
